Not at all. The implication is that if few people use a feature, few people will be affected if you remove it. They may be really, really upset, but there won't be many of them.
I'm sorry, but for 99 cents you don't get complete control over my time and decision making process. Feel free to make suggestions, but for the love of God don't "tell me" that "I need" to make feature X for you. I particularly enjoy 1-3 star reviews that say it's great but it needs X to improve review. As if they would actually come back and change it when it gets X. I promise they don't.
If you remove that one feature under my feet, the app is to me worth nothing. I would be ok using the old version of application that still has that feature, but in case of a service or phone app where I simply can't use the old version or easily rollback to the one, I would ask for refund, regardless of the original price.
Grrr.
The implication behind this statement is that if most users don't use something, the one's that do don't find it useful.
I regard this implication to be false, and damaging.
> It can help rest of the users (make the app more simple)
If a user interface is well designed, then features that someone doesn't use won't get in their way.
